CortexDesk is a local desktop assistant for macOS teams that need speed and privacy. It understands natural language, uses local tools, and asks for approval before sensitive actions.
No cloud. No subscriptions. No compromise.
CortexDesk is designed for professionals, not for autonomous internet agents. It focuses on local execution, explicit approvals, and predictable outcomes.
You can ask in natural language and CortexDesk routes to local tools for calendar, reminders, drafting, search, and reasoning support.
CortexDesk does not aim to automate every website and app without guardrails. It is not an always-on cloud operator.
V1 is focused: local assistant loop, approvals, memory, calendar/reminders, voice, and specialist routing. Office server and full remote automation come later.
Every request passes through a coordinated pipeline of specialized models — all running locally, all under your control.
You type a command, ask a question, or delegate a task. CortexDesk accepts natural language or structured directives.
Local onlyThe orchestration core classifies intent and routes your request to the right micro-model combination — no guessing, no bloat.
On-device inferenceSpecialized models handle their domain in parallel: safety screening, writing assistance, calendar logic, numerical reasoning.
Parallel inferenceBefore any action executes — sending email, editing a file, accessing calendar — you see exactly what will happen and approve it.
Explicit approvalRather than one monolithic model doing everything, CortexDesk routes tasks to purpose-built micro-models — each optimized, lightweight, and isolated.
The central routing layer that classifies, decomposes, and delegates. Runs entirely in-process. No syscalls leave the orchestration sandbox without an approval token.
Pre-screens all inputs. Flags policy conflicts before execution. Cannot be bypassed by prompts or roleplay.
Reads and writes calendar events locally via CalendarKit. Understands time, conflicts, and context.
Drafts, edits, and formats documents. Adapts to your voice, your contacts, your context.
Writes and refactors code. Runs sandboxed in local execution with no outbound access.
Symbolic and numeric reasoning for financial and legal work. Deterministic. No LLM guessing.
Manages your local context store. Retrieves selectively. Encrypted at rest. Always yours.
For professionals who handle client data, financial records, or privileged communications — the cloud is not an option.
Client data, case notes, financial models — none of it ever touches a remote server. Privilege is preserved. Compliance is structural, not promised.
Local inference means sub-100ms first token on Apple Silicon. No queuing, no rate limits, no degraded service during outages. Your machine is the server.
No monthly subscription. No per-seat pricing. No API costs that scale with usage. Pay once, run forever. Your workflow is never held hostage to a pricing model.
CortexDesk never acts autonomously. Before any file is modified, email sent, or system call made — you see a plain-language summary and choose to allow or deny.
Every proposed action is legible.
No hidden background processes.
No silent writes.
CortexDesk tells you exactly what it wants to do — and waits.
